CVE-2025-45525 (GCVE-0-2025-45525)

Vulnerability from cvelistv5 – Published: 2025-06-17 00:00 – Updated: 2025-08-26 18:51 Disputed
VLAI?
Summary
A NULL pointer dereference vulnerability has been identified in the JavaScript library microlight version 0.0.7, a lightweight syntax highlighting library. When processing elements with non-standard CSS color values, the library fails to validate the result of a regular expression match before accessing its properties, leading to an uncaught TypeError and potential application crash. NOTE: this is disputed by multiple parties because there is no common scenario in which an adversary can insert those non-standard values.

CVE-2025-45526 (GCVE-0-2025-45526)

Vulnerability from cvelistv5 – Published: 2025-06-17 00:00 – Updated: 2025-06-26 16:10 Disputed
VLAI?
Summary
A denial of service (DoS) vulnerability has been identified in the JavaScript library microlight version 0.0.7. This library, used for syntax highlighting, does not limit the size of textual content it processes in HTML elements with the microlight class. When excessively large content (e.g., 100 million characters) is processed, the reset function in microlight.js consumes excessive memory and CPU resources, causing browser crashes or unresponsiveness. An attacker can exploit this vulnerability by tricking a user into visiting a malicious web page containing a microlight element with large content, resulting in a denial of service. NOTE: this is disputed by multiple parties because a large amount of memory and CPU resources is expected to be needed for content of that size.
